Seth Thomas 124 mainspring service...ugh!!

[LittleWatchShop]

I picked a nice ST 124 for $75.  It is very very close to the E701 electric clock (I have serviced maybe four or five), so I am familiar with all of the little calibrations you must do during assembly.

This is the first fully spring-driven version I have worked on.  The mainsprings were a real pain.  The barrels are riveted in, so I did not think I could use the mainspring tool, so I did it by hand.  It was not horrible, but challenging.  Anyway, it is done now.  In retrospect, there might have been a way to do this on the winder if I manufactured an arbor just for this purpose.  Who knows.

They are nasty to work with. Who ever designed it that way they need shooting.

Update.  Clock is assembled and running like a champ!  Previous clockmaker replace the convex glass with a flat glass.  LOL It did not allow the bezel to close.  Yesterday, I was driving home from Bryan Tx and passed through the little town of Kyle.  The wife was driving so I was on FB marketplace.  Up popped a little Smiths-Enfield clock for 20 bucks.  It was on my way, so I got it. Next day, I stole the convex glass from it and put it on my ST 124.  The donor's dilemma!!
